Examples of javax.cache.CacheManager.destroyCache()

javax.cache.CacheManager.destroyCache()

Destroys a specifically named and managed {@link Cache}. Once destroyed a new {@link Cache} of the same name but with a different {@link Configuration} may be configured.

This is equivalent to the following sequence of method calls:

{@link Cache#clear()}
{@link Cache#close()}

followed by allowing the name of the {@link Cache} to be used for other{@link Cache} configurations.

From the time this method is called, the specified {@link Cache} is notavailable for operational use. An attempt to call an operational method on the {@link Cache} will throw an {@link IllegalStateException}. @param cacheName the cache to destroy @throws IllegalStateException if the {@link CacheManager}{@link #isClosed()} @throws NullPointerException if cacheName is null @throws SecurityException when the operation could not be performeddue to the current security settings

        cache.removeAll(keys);


        assertNull(cache.get(key1));
        assertNull(cache.get(key2));


        cacheManager.destroyCache(cacheName);
    }


    @Test
    public void testCompletionTest()
            throws InterruptedException {

        String value2 = cache.get(key);
        assertEquals(value1, value2);
        cache.remove(key);
        assertNull(cache.get(key));


        cacheManager.destroyCache(cacheName);
        assertNull(cacheManager.getCache(cacheName));


        Cache<Integer, String> cache1 = cacheManager.createCache(cacheName, config);
        assertNotNull(cache1);
    }
